Procedure Step by Step:

Salaatul Haajat can be performed when one is in need or in any difficulty. The Prophet (Sallallahu Alaihi Wasallam) stated that whoever is in need of something or in difficulty should:
1: First make perfect wudhu, observing all the rules and aadaab of wudhu.
2: Then perform two raka'ts Salaat.
3: After the Salaat recite the praises of Allah Subhanahu wa Ta'ala and recite Durood Shareef.
4: One may recite any amount and any formula of praises - Tahmeed and Tasbeeh - as well as any amount of Durood Shareef.
5: Thereafter make a fervent Dua for the fulfilment of your need or difficulty.
Wassalaamu Alaykum wa Rahmatullahi wa Barakatuh.

Conclusion: There is no Saheeh Hadith about this prayer, so it is not prescribed for the Muslim to offer it. What is narrated in the saheeh Sunnah of prayers, dua's and adhkaar is sufficient for him.

Secondly:

With regard to the questioner saying that she tried it and found it beneficial, this was said by others before her, but issues of sharee’ah cannot be proven in this way.

Al-Shawkaani (may Allah have mercy on him) said:

The Sunnah cannot be proven merely from experience, and the acceptance of du’aa’ does not necessarily mean that this was narrated in a sound from the Messenger of Allaah (peace and blessings of Allaah be upon him). Allaah may answer a du’aa’ even when one does not seek to draw close to Him by means of the Sunnah, for He is the Most Merciful of those who show mercy, or the answer may be a kind of test that may lead a person further away from Allaah.

Shaykh Saalih al-Fawzaan (may Allaah preserve him) said:

As for what is said about So and so having tried it and found it to be true, all of that does not indicate that the hadeeth is saheeh. The fact that a person tried something and got what he wanted does not prove that which is said about it or narrated concerning it is correct, because it may be decreed that he gets this thing, or it may be a test and trial for the one who does that. Achieving one’s aim does not mean that what is narrated concerning it is correct. End quote.
